As said above, try to relax... plan ahead, not in terms of completing applications (trust me, you'll get them done in time), but in terms of having something to occupy your time/mind/energy in the months between submitting apps and waiting for decisions. Chances are you will be a senior, you may even be part time, and suddenly you will go from the hugely active task of completing applications to the insanely passive task of waiting for responses. I would tell myself to sign up for a running race in early May and spend the spring training for the race. I would tell myself to set a goal of learning a new skill or hobby. You will need something to pass the time instead of just manically refreshing this website, CSDCAS, and the online portals for your programs. Something else, I would set a time (two times max) that I am allowed to check online for results/decisions etc. You will drive yourself insane refreshing webpages. Just relax! You have already done all the hard work! You will get in somewhere!
